Statement I: If a sphere of mass `m`moving with speed `u` undergoes a perfectly elastic head-on collision with another sphere of heavier mass `M` at rest (`M gt m`), then direction of velocity of sphere of mass `m` is reversed due to collision (no external force acts on system of two spheres).
Statement II: During a collision of spheres of unequal masses, the heavier mass exerts more force on the lighter mass in comparison to the force which lighter mass exerts on the heavier one,
